[0002] In the chip production process, chip testing is an important link. The existing chip small batch semi-automatic test or test verification is generally carried out on the chip test bench, and the chip test bench generally has a horizontal fixing plate for fixing the chip test fixture horizontally fixed on several vertical and parallel step plates, and the number of steps on the step plate, the number of horizontal fixing plates and the number of chip test fixtures fixed on the horizontal fixing plate are generally determined according to actual needs. During testing, the data and power transmission lines inserted into the chip test fixture extend out from the rear side of the step plate and are connected to the test system (including the hub of the purchased adapter transmission line and the computer with test software). When multiple chip test fixtures are fixed on the multiple horizontal fixing plates, the transmission lines extending out from the rear side of the step plate will be messy, and when the transmission lines are accidentally touched during the operation test, the end of the transmission line inserted into the chip test fixture may be loose, causing the test of one or more chip test fixtures to fail normally. In the subsequent confirmation and maintenance process of the transmission line connected to the chip test fixture, the messy transmission lines may interfere with each other and cause a chain reaction to accidentally touch other transmission lines, so the confirmation process is more troublesome, reducing the test efficiency, and the accidental touch during the test process may also cause inaccurate test results. When the corresponding limiting structure for the transmission line is set on the rear side of the chip test bench, the operation space is small and the maintenance needs to be careful, which is low in efficiency.
